Number of stars players in Vakif and Eczacibasi is arguable and that is not basic diference between Ecz and Vakif in previous years. IMO that was better local player stronger MB and BETTER coach and team chemistry. Results of Vakif and Eczacibasi are not way of compare Zhu and Boskovic as player. One more important thing you mentioned before is that their starting point were diferent, but you obviously dont know from where Boskovic does. She played before Turkey in Vizura in Serbian league which is definetly worse than CVL and without lot of money.
Both of them started at no name team / club. Boskovic has an earlier starting point going to strong / big club because she controls her destiny she can sign any contract without approval from the league. Whereas Zhu was under Henan club which controlled basically her destiny just like most 🇨🇳 players. Guidetti was interested to sign Zhu when he saw her 2013; it was only 2016 Guidetti got Zhu to join his team. Boskovic and Zhu could had been teammates in Vitra, but there was a condition from her team that Zhu had to play for Henan for the National games. Vitra did not agreed, so Zhu signed with Vakif.
